Let’s address the issue of a Citroen C4 Grand Picasso where the Start & Stop system is not functioning correctly. On these vehicles, the Start & Stop is not activated by the starter motor, but by the alternator.

If the tensioner for the belt does not apply sufficient pressure, the belt slips (you can hear a strange noise in the video), and consequently, the alternator fails to restart the vehicle, which must be manually restarted each time. The solution is to replace the auxiliary belt, which also drives the alternator, and the tensioner, which should always be replaced in these cases.

This way, the problem is completely resolved.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
